问题描述
我有一个jquery函数,可以检测下拉列表中的更改项。我想使用jquery更改CurrentCulture,以更改.net core中的LocalizatedValue,这是包含我的试用版的jquery方法
$('#dropdownList li').find("a").click(function () {
$('#dropdown-button').html($(this).html());
$("#dropdown-button").val($(this).text());
if (document.getElementById('dropdown-button').innerText === "Arab") {
Globalization.locale("ar")
} else if (document.getElementById('dropdown-button').innerText === "French") {
Globalization.locale("fr")
} else if (document.getElementById('dropdown-button').innerText === "English") {
Globalization.locale("en")
}
});
});
在那里,我需要使用cs代码的当前文化信息
private string GetString(string name)
{
var query = localization.Where(l => l.LocalizedValue.Keys.Any(lv => lv == CultureInfo.CurrentCulture.Name));
var value = query.FirstOrDefault(l => l.Key == name);
return value.LocalizedValue[CultureInfo.CurrentCulture.Name];
}
解决方法
这是基于official docs的有效演示:
1。在根项目中创建SharedResource.cs
:
public class SharedResource
{
}
2。在SharedResource.fr.resx
文件夹中创建Resources
以添加资源。Resources
文件夹位于根项目中。
@using Microsoft.AspNetCore.Mvc.Localization
@using Microsoft.Extensions.Localization
@using Microsoft.AspNetCore.Builder
@using Microsoft.AspNetCore.Localization
@using Microsoft.Extensions.Options
@inject IStringLocalizer<SharedResource> SharedLocalizer
@inject IOptions<RequestLocalizationOptions> LocOptions
@{
var requestCulture = Context.Features.Get<IRequestCultureFeature>();
var cultureItems = LocOptions.Value.SupportedUICultures
.Select(c => new SelectListItem { Value = c.Name,Text = c.DisplayName })
.ToList();
var returnUrl = string.IsNullOrEmpty(Context.Request.Path) ? "~/" : $"~{Context.Request.Path.Value}";
}
<div title="@SharedLocalizer["Request culture provider:"] @requestCulture?.Provider?.GetType().Name">
<form id="selectLanguage" asp-controller="Home"
asp-action="SetLanguage" asp-route-returnUrl="@returnUrl"
method="post" class="form-horizontal" role="form">
<label asp-for="@requestCulture.RequestCulture.UICulture.Name">@SharedLocalizer["Language:"]</label>
<select name="culture" onchange="this.form.submit();"
asp-for="@requestCulture.RequestCulture.UICulture.Name"
asp-items="cultureItems">
</select>
</form>
</div>
<h1>@SharedLocalizer["Home Page"]</h1>
4.HomeController:
public class HomeController : Controller
{
[HttpPost]
public IActionResult SetLanguage(string culture,string returnUrl)
{
Response.Cookies.Append(
CookieRequestCultureProvider.DefaultCookieName,CookieRequestCultureProvider.MakeCookieValue(new RequestCulture(culture)),new CookieOptions { Expires = DateTimeOffset.UtcNow.AddYears(1) }
);
return LocalRedirect(returnUrl);
}
}
5.Startup.cs:
public void ConfigureServices(IServiceCollection services)
{
services.AddLocalization(options => options.ResourcesPath = "Resources");
services.AddControllersWithViews()
.AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
.AddDataAnnotationsLocalization();
services.Configure<RequestLocalizationOptions>(options =>
{
var supportedCultures = new[]
{
new CultureInfo("en-US"),new CultureInfo("fr")
};
options.DefaultRequestCulture = new RequestCulture(new CultureInfo("en-US"),new CultureInfo("en-US"));
options.SupportedCultures = supportedCultures;
options.SupportedUICultures = supportedCultures;
});
}
public void Configure(IApplicationBuilder app,IWebHostEnvironment env)
{
var supportedCultures = new[] { "en-US","fr" };
var localizationOptions = new RequestLocalizationOptions().SetDefaultCulture(supportedCultures[0])
.AddSupportedCultures(supportedCultures)
.AddSupportedUICultures(supportedCultures);
app.UseRequestLocalization(localizationOptions);
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",pattern: "{controller=Home}/{action=Index}/{id?}");
});
}
结果:
